Record and playback 1 - 8 audio channels in manual switch, or relay mode with individual channel selection or 8 channels in random or sequence playback mode with a single switch, relay or input signal, all with one unique digital memory sound chip and controller.

Here is a very simple audio controller that when triggered by pressing the single on-board button or by dry contact closure at the trigger terminal, will cause the player to play back 1 to 10 MP3 files that are stored on a USB flash device (USB pen drive not included).
